Maybe there is a kind of river/channel too small to be seen linking the inland ocean to the main ocean or even a tidal effect. Fusion has been 20 years away since the 1960s, fusion by 2030 for much of our power is very optimistic. However we should see coal in decline and renewables steadily increasing.
Good to see the UK report today on reduced coal. However, on the downside, the report is very frustrating in that it says UK carbon emisions fall to 1894 levels but there's no clue as to whether they are including aviation, shipping, offshoring of carbon emissions to China. A rather useless statistic.
